一.介绍
Vue.js 是什么
Vue (读音 /vjuː/,类似于 view) 是一套用于构建用户界面的渐进式框架。与其它大型框架不同的是,Vue 被设计为可以自底向上逐层应用。Vue 的核心库只关注视图层,不仅易于上手,还便于与第三方库或既有项目整合。另一方面,当与现代化的工具链以及各种支持类库结合使用时,Vue 也完全能够为复杂的单页应用提供驱动。
二.创建初始化项目
这里不在详细说明,我们的分页演示只需要vue和vue-router就可以了,我们直接构建项目和设置配置。
main.js:
import Vue from 'vue' import App from './App.vue' import VueRouter from 'vue-router' import pageHome from './pageHome.vue' import pageNews from './pageNews.vue' import pageInfo from './pageInfo.vue' //路由配置 Vue.use(VueRouter); var routes = [ { path: '/', component: pageHome}, { path: '/pageNews', component: pageNews}, { path: '/pageInfo', component: pageInfo} ] var router = new VueRouter({ routes: routes // (缩写)相当于 routes: routes }) new Vue({ el: '#app', router, render: h => h(App) })
App.vue:
<template> <div id="app"> <h3>{{msg}}</h3> <ul> <li><router-link to="/">pageHome</router-link></li> <li><router-link to="/pageNews">pageNews</router-link></li> <li><router-link to="/pageInfo">pageInfo</router-link></li> </ul> <div> <router-view></router-view> </div> </div> </template> <script> export default { name: 'app', data () { return { msg: '分页组件:DiVuePage ' } } } </script> <style> #app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px; } </style>
pageHome.vue:
<template> <div class="page"> <p>//模拟ajax数据 1-7页</p> <ul class="ull"> <li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">内容:{{item.text}}</span></li> </ul> </div> </template> <script> export default { name: 'pageHome', data () { return { currentpage:0, list: [], allpage:"", nextpage:false } }, methods:{ getajaxlist:function(currentpage){ var that=this; var list=[]; var allpage=""; var nextpage=""; //模拟ajax数据 1-7页 setTimeout(function(){ if(currentpage==1){ list=[ {id:1,text:"111111"}, {id:2,text:"222222"}, {id:3,text:"3333333333"}, {id:4,text:"44444444444"}, {id:5,text:"555555555"}, ] allpage=7 nextpage=true; }else if(currentpage==2){ list=[ {id:1,text:"66666666"}, {id:2,text:"7777777777"}, {id:3,text:"8888888888"}, {id:4,text:"99999999999"}, {id:5,text:"101010"}, ] allpage=7 nextpage=true; }else if(currentpage==3){ list=[ {id:1,text:"111111111111111"}, {id:2,text:"121212"}, {id:3,text:"131313"}, {id:4,text:"141414"}, {id:5,text:"15515"}, ] allpage=7 nextpage=true; }else if(currentpage==4){ list=[ {id:1,text:"161616"}, {id:2,text:"171717"}, {id:3,text:"181818"}, {id:4,text:"191919"}, {id:5,text:"202020"}, ] allpage=7 nextpage=true; }else if(currentpage==5){ list=[ {id:1,text:"2121"}, {id:2,text:"22222"}, {id:3,text:"232323"}, {id:4,text:"242424"}, {id:5,text:"252525"}, ] allpage=7 nextpage=true; }else if(currentpage==6){ list=[ {id:1,text:"2626"}, {id:2,text:"2727"}, {id:3,text:"2828"}, {id:4,text:"2929"}, {id:5,text:"3030"}, ] allpage=7 nextpage=true; }else if(currentpage==7){ list=[ {id:1,text:"3131"}, {id:2,text:"3232"} ] allpage=7 nextpage=false; }; that.currentpage=currentpage; that.list=list; that.allpage=allpage; that.nextpage=nextpage; },200); } }, created:function(){ //模拟生成第一页数据 this.getajaxlist(1); } } </script> <style> ul{ list-style:none;} ull{ margin:100px auto; width:1000px;line-height:30px;} li{height:30px;} .l{float:left;width:300px;} .r{float:left;width:600px;} </style>
pageInfo.vue:
<template> <div class="page"> <p>//模拟ajax数据 1-3页</p> <ul class="ull"> <li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">内容:{{item.text}}</span></li> </ul> </div> </template> <script> export default { name: 'pageInfo', data () { return { currentpage:0, list: [], allpage:"", nextpage:false } }, methods:{ getajaxlist:function(currentpage){ var that=this; var list=[]; var allpage=""; var nextpage=""; //模拟ajax数据 1-3页 setTimeout(function(){ if(currentpage==1){ list=[ {id:1,text:"111111"}, {id:2,text:"222222"}, {id:3,text:"3333333333"}, {id:4,text:"44444444444"}, {id:5,text:"555555555"}, ] allpage=3 nextpage=true; }else if(currentpage==2){ list=[ {id:1,text:"66666666"}, {id:2,text:"7777777777"}, {id:3,text:"8888888888"}, {id:4,text:"99999999999"}, {id:5,text:"101010"}, ] allpage=3 nextpage=true; }else if(currentpage==3){ list=[ {id:1,text:"111111111111111"}, {id:2,text:"121212"}, {id:3,text:"131313"}, {id:4,text:"141414"}, {id:5,text:"15515"}, ] allpage=3 nextpage=false; } that.currentpage=currentpage; that.list=list; that.allpage=allpage; that.nextpage=nextpage; },200); } }, created:function(){ //模拟生成第一页数据 this.getajaxlist(1); } } </script> <style> ul{ list-style:none;} ull{ margin:100px auto; width:1000px;line-height:30px;} li{height:30px;} .l{float:left;width:300px;} .r{float:left;width:600px;} </style>

三.分页静态结构和样式
divuePage.vue:
<template> <div class="DiReactPage"> <div class="DiReactPage-btn">第一页</div> <div class="DiReactPage-btn disable">上一页</div> <div class="DiReactPage-page"> <span class="active">1</span> <span>2</span> <span>3</span> <span>4</span> </div> <div class="DiReactPage-btn">下一页</div> <div class="DiReactPage-btn">最后一页</div> <div class="DiReactPage-btn">总4页</div> <input class="DiReactPage-input" type="text" /> <button class="DiReactPage-btn">跳转</button> </div> </template> <script> export default { name: 'divuePage', data () { return { pages:[1,2,3,4,5] } }, methods:{ } } </script> <style> .DiReactPage{ height:30px; line-height:30px; text-align:center;} .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;} .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;} .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;} .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;} .DiReactPage .DiReactPage-page span.active{ color:#09F; } .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; } </style>
main.js注册:
import Vue from 'vue' import App from './App.vue' import VueRouter from 'vue-router' import pageHome from './pageHome.vue' import pageNews from './pageNews.vue' import pageInfo from './pageInfo.vue' //注册组件 import divuePage from './divuePage.vue' Vue.component('divue-page', divuePage) //路由配置 Vue.use(VueRouter); var routes = [ { path: '/', component: pageHome}, { path: '/pageNews', component: pageNews}, { path: '/pageInfo', component: pageInfo} ] var router = new VueRouter({ routes: routes // (缩写)相当于 routes: routes }) new Vue({ el: '#app', router, render: h => h(App) })
pageHome.vue引用:
<template> <div class="page"> <p>//模拟ajax数据 1-7页</p> <ul class="ull"> <li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">内容:{{item.text}}</span></li> </ul> <divue-page></divue-page> </div> </template> <script> export default { name: 'pageHome', data () { return { currentpage:0, list: [], allpage:"", nextpage:false } }, methods:{ getajaxlist:function(currentpage){ var that=this; var list=[]; var allpage=""; var nextpage=""; //模拟ajax数据 1-7页 setTimeout(function(){ if(currentpage==1){ list=[ {id:1,text:"111111"}, {id:2,text:"222222"}, {id:3,text:"3333333333"}, {id:4,text:"44444444444"}, {id:5,text:"555555555"}, ] allpage=7 nextpage=true; }else if(currentpage==2){ list=[ {id:1,text:"66666666"}, {id:2,text:"7777777777"}, {id:3,text:"8888888888"}, {id:4,text:"99999999999"}, {id:5,text:"101010"}, ] allpage=7 nextpage=true; }else if(currentpage==3){ list=[ {id:1,text:"111111111111111"}, {id:2,text:"121212"}, {id:3,text:"131313"}, {id:4,text:"141414"}, {id:5,text:"15515"}, ] allpage=7 nextpage=true; }else if(currentpage==4){ list=[ {id:1,text:"161616"}, {id:2,text:"171717"}, {id:3,text:"181818"}, {id:4,text:"191919"}, {id:5,text:"202020"}, ] allpage=7 nextpage=true; }else if(currentpage==5){ list=[ {id:1,text:"2121"}, {id:2,text:"22222"}, {id:3,text:"232323"}, {id:4,text:"242424"}, {id:5,text:"252525"}, ] allpage=7 nextpage=true; }else if(currentpage==6){ list=[ {id:1,text:"2626"}, {id:2,text:"2727"}, {id:3,text:"2828"}, {id:4,text:"2929"}, {id:5,text:"3030"}, ] allpage=7 nextpage=true; }else if(currentpage==7){ list=[ {id:1,text:"3131"}, {id:2,text:"3232"} ] allpage=7 nextpage=false; }; that.currentpage=currentpage; that.list=list; that.allpage=allpage; that.nextpage=nextpage; },200); } }, created:function(){ //模拟生成第一页数据 this.getajaxlist(1); } } </script> <style> ul{ list-style:none;} ull{ margin:100px auto; width:1000px;line-height:30px;} li{height:30px;} .l{float:left;width:300px;} .r{float:left;width:600px;} </style>

四.分页组件实现逻辑分析
我们分析一下如何实现我们的分页组件:
从分页组件考虑:
分页组件需要显示页数,那么就需要传递给分页组件总用多少页这个状态,
上一页和下一页存在不可用状态,在第一页上一页不可用,所以要把当前所在页数传递,同样页数的焦点位置也需要它判断,
然后就是方法,我们页数和按钮的点击都是发起请求,携带的参数就是当前点击的页数,
1.总页数,当前所在页,可在父组件传递进入
2.发起请求的方法可以通过组件交互通信实现
1的数据都是接口会返回给我们的,我们直接以属性传递即可:
2的实现也很简单,我们其实已经处理模拟使用过了:
我们只需要自定义事件,让分页组件$emit即可:
pageHome.vue:
<template> <div class="page"> <p>//模拟ajax数据 1-7页</p> <ul class="ull"> <li v-for="(item,index) in list"><span class="l">id:{{item.id}}</span> <span class="r">内容:{{item.text}}</span></li> </ul> <divue-page v-bind:currentpage="currentpage" v-bind:allpage="allpage" v-on:getajaxlist="getajaxlist"></divue-page> </div> </template> <script> export default { name: 'pageHome', data () { return { currentpage:0, list: [], allpage:"", nextpage:false } }, methods:{ getajaxlist:function(currentpage){ var that=this; var list=[]; var allpage=""; var nextpage=""; //模拟ajax数据 1-7页 setTimeout(function(){ if(currentpage==1){ list=[ {id:1,text:"111111"}, {id:2,text:"222222"}, {id:3,text:"3333333333"}, {id:4,text:"44444444444"}, {id:5,text:"555555555"}, ] allpage=7 nextpage=true; }else if(currentpage==2){ list=[ {id:1,text:"66666666"}, {id:2,text:"7777777777"}, {id:3,text:"8888888888"}, {id:4,text:"99999999999"}, {id:5,text:"101010"}, ] allpage=7 nextpage=true; }else if(currentpage==3){ list=[ {id:1,text:"111111111111111"}, {id:2,text:"121212"}, {id:3,text:"131313"}, {id:4,text:"141414"}, {id:5,text:"15515"}, ] allpage=7 nextpage=true; }else if(currentpage==4){ list=[ {id:1,text:"161616"}, {id:2,text:"171717"}, {id:3,text:"181818"}, {id:4,text:"191919"}, {id:5,text:"202020"}, ] allpage=7 nextpage=true; }else if(currentpage==5){ list=[ {id:1,text:"2121"}, {id:2,text:"22222"}, {id:3,text:"232323"}, {id:4,text:"242424"}, {id:5,text:"252525"}, ] allpage=7 nextpage=true; }else if(currentpage==6){ list=[ {id:1,text:"2626"}, {id:2,text:"2727"}, {id:3,text:"2828"}, {id:4,text:"2929"}, {id:5,text:"3030"}, ] allpage=7 nextpage=true; }else if(currentpage==7){ list=[ {id:1,text:"3131"}, {id:2,text:"3232"} ] allpage=7 nextpage=false; }; that.currentpage=currentpage; that.list=list; that.allpage=allpage; that.nextpage=nextpage; },200); } }, created:function(){ //模拟生成第一页数据 this.getajaxlist(1); } } </script> <style> ul{ list-style:none;} ull{ margin:100px auto; width:1000px;line-height:30px;} li{height:30px;} .l{float:left;width:300px;} .r{float:left;width:600px;} </style>
五.分页组件逻辑编写
divuePage.vue我们接受了这些传递的内容,总页数和当前所在页,然后点击第一页触发自定义事件,传递给父组件一个1,获取第一页数据:
<template> <div class="DiReactPage"> <div class="DiReactPage-btn" v-on:click="clickFirst">第一页</div> <div class="DiReactPage-btn disable">上一页</div> <div class="DiReactPage-page"> <span class="active">1</span> <span>2</span> <span>3</span> <span>4</span> </div> <div class="DiReactPage-btn">下一页</div> <div class="DiReactPage-btn">最后一页</div> <div class="DiReactPage-btn">总4页</div> <input class="DiReactPage-input" type="text" /> <button class="DiReactPage-btn">跳转</button> </div> </template> <script> export default { name: 'divuePage', props:["currentpage","allpage"], methods:{ clickFirst:function(){//点击第一页 this.$emit("getajaxlist",1); } } } </script> <style> .DiReactPage{ height:30px; line-height:30px; text-align:center;} .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;} .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;} .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;} .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;} .DiReactPage .DiReactPage-page span.active{ color:#09F; } .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; } </style>
1.页数显示
我们的首要工作就是把页数显示出来,我们已经接收了总页数,其实这个问题很容易解决,我们设置一个计算属性,属性依据总页数生成一个数组,从1到n即可:
显示:
这样还不够健壮,还有一个就是总页数5做分界线,大于5就显示当前到后4个,
比如在第3页,显示:3 4 5 6 7
第2页,显示:2 3 4 5 6
好了我们加入一些小的逻辑判断:
我们要给当前页加一个类名标识,已经获取当前的页数了,我们加一个判断就可以了,在v-for中:
我们在加入点击事件,拿到点击的item就是要请求后台数据的参数page:
定义这个方法:
完整代码:
<template> <div class="DiReactPage"> <div class="DiReactPage-btn" v-on:click="clickFirst">第一页</div> <div class="DiReactPage-btn disable">上一页</div> <div class="DiReactPage-page"> <span v-for="(item,index) in pages" v-bind:class="{active:currentpage==item}" v-on:click="clickCurrent(item)">{{item}}</span> </div> <div class="DiReactPage-btn">下一页</div> <div class="DiReactPage-btn">最后一页</div> <div class="DiReactPage-btn">总4页</div> <input class="DiReactPage-input" type="text" /> <button class="DiReactPage-btn">跳转</button> </div> </template> <script> export default { name: 'divuePage', computed:{ pages:function(){ var arr=[]; if(this.allpage>5){ if(this.currentpage+5>this.allpage){ for(var i=this.currentpage;i<=this.allpage;i++){ arr.push(i); }; }else{ for(var i=this.currentpage;i<this.currentpage+5;i++){ arr.push(i); }; }; }else{ for(var i=1;i<=this.allpage;i++){ arr.push(i); }; } return arr; } }, props:["currentpage","allpage"], methods:{ clickFirst:function(){//点击第一页 this.$emit("getajaxlist",1); }, clickCurrent:function(item){ this.$emit("getajaxlist",item); } } } </script> <style> .DiReactPage{ height:30px; line-height:30px; text-align:center;} .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;} .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;} .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;} .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;} .DiReactPage .DiReactPage-page span.active{ color:#09F; } .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; } </style>
效果测试:
2.第一页和最后一页处理
这个很简单,只是传递page参数,我们已经获取总页数,直接设置即可!
3.上一页和下一页处理
这个对比第一页需要加入特殊的处理,当前是第一页,这个按钮就不可用状态,下一页一样的逻辑判断当前是不是在最后一页:
调用位置加入事件,在加一个是否可用的类名:
全部代码:
<template> <div class="DiReactPage"> <div class="DiReactPage-btn" v-on:click="clickFirst">第一页</div> <div class="DiReactPage-btn" v-on:click="clickPrev" v-bind:class="{disable:currentpage==1}">上一页</div> <div class="DiReactPage-page"> <span v-for="(item,index) in pages" v-bind:class="{active:currentpage==item}" v-on:click="clickCurrent(item)">{{item}}</span> </div> <div class="DiReactPage-btn" v-on:click="clickNext" v-bind:class="{disable:currentpage==allpage}">下一页</div> <div class="DiReactPage-btn" v-on:click="clickLast">最后一页</div> <div class="DiReactPage-btn">总4页</div> <input class="DiReactPage-input" type="text" /> <button class="DiReactPage-btn">跳转</button> </div> </template> <script> export default { name: 'divuePage', computed:{ pages:function(){ var arr=[]; if(this.allpage>5){ if(this.currentpage+5>this.allpage){ for(var i=this.currentpage;i<=this.allpage;i++){ arr.push(i); }; }else{ for(var i=this.currentpage;i<this.currentpage+5;i++){ arr.push(i); }; }; }else{ for(var i=1;i<=this.allpage;i++){ arr.push(i); }; } return arr; } }, props:["currentpage","allpage"], methods:{ clickFirst:function(){//点击第一页 this.$emit("getajaxlist",1); }, clickCurrent:function(item){ this.$emit("getajaxlist",item); }, clickLast:function(){//点击最后一页 this.$emit("getajaxlist",this.allpage); }, clickPrev:function(){//点击上一页 if(this.currentpage-1<1){ return false; } this.$emit("getajaxlist",this.currentpage-1); }, clickNext:function(){//点击下一页 if(this.currentpage+1>this.allpage){ return false; } this.$emit("getajaxlist",this.currentpage+1); } } } </script> <style> .DiReactPage{ height:30px; line-height:30px; text-align:center;} .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;} .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;} .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;} .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;} .DiReactPage .DiReactPage-page span.active{ color:#09F; } .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; } </style>
效果测试:
4.跳页处理
这个我们获取输入框的值,直接调用,不过对输入的内容必须有一些判断限制:
加一个data:
使用位置:
5.显示总页数
这个是最简单的:
六.分页全部代码和测试
divuePage.vue:
<template> <div class="DiReactPage"> <div class="DiReactPage-btn" v-on:click="clickFirst">第一页</div> <div class="DiReactPage-btn" v-on:click="clickPrev" v-bind:class="{disable:currentpage==1}">上一页</div> <div class="DiReactPage-page"> <span v-for="(item,index) in pages" v-bind:class="{active:currentpage==item}" v-on:click="clickCurrent(item)">{{item}}</span> </div> <div class="DiReactPage-btn" v-on:click="clickNext" v-bind:class="{disable:currentpage==allpage}">下一页</div> <div class="DiReactPage-btn" v-on:click="clickLast">最后一页</div> <div class="DiReactPage-btn">总{{allpage}}页</div> <input class="DiReactPage-input" type="text" v-model="skipvalue" /> <button class="DiReactPage-btn" v-on:click="clickSkip">跳转</button> </div> </template> <script> export default { name: 'divuePage', computed:{ pages:function(){ var arr=[]; if(this.allpage>5){ if(this.currentpage+5>this.allpage){ for(var i=this.currentpage;i<=this.allpage;i++){ arr.push(i); }; }else{ for(var i=this.currentpage;i<this.currentpage+5;i++){ arr.push(i); }; }; }else{ for(var i=1;i<=this.allpage;i++){ arr.push(i); }; } return arr; } }, data:function(){ return { skipvalue:"" } }, props:["currentpage","allpage"], methods:{ clickFirst:function(){//点击第一页 this.$emit("getajaxlist",1); }, clickCurrent:function(item){ this.$emit("getajaxlist",item); }, clickLast:function(){//点击最后一页 this.$emit("getajaxlist",this.allpage); }, clickPrev:function(){//点击上一页 if(this.currentpage-1<1){ return false; } this.$emit("getajaxlist",this.currentpage-1); }, clickNext:function(){//点击下一页 if(this.currentpage+1>this.allpage){ return false; } this.$emit("getajaxlist",this.currentpage+1); }, clickSkip:function(){//点击下一页 if(isNaN(this.skipvalue)){ console.log("必须是数字") return false; } if(this.skipvalue<1 || this.skipvalue>this.allpage){ console.log("超过范围") return false; } this.$emit("getajaxlist",this.skipvalue); } } } </script> <style> .DiReactPage{ height:30px; line-height:30px; text-align:center;} .DiReactPage .DiReactPage-btn{ display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; border-radius:4px; background:#09F; cursor:pointer;} .DiReactPage .DiReactPage-btn.disable{ background:#999;cursor:not-allowed;} .DiReactPage .DiReactPage-page{ display:inline-block; height:30px; line-height:30px; margin:0 20px;} .DiReactPage .DiReactPage-page span{display:inline-block; height:30px; line-height:30px; padding:0 5px; margin:0 5px; color:#000; cursor:pointer;} .DiReactPage .DiReactPage-page span.active{ color:#09F; } .DiReactPage .iReactPage-input{ width:100px; border:1px solid #666; border-radius:4px;height:30px; line-height:30px; } </style>
我们现在在pageHome.vue做了使用,这个模拟数据包含7页,我们在另外两个组件也使用分页组件,测试小于5页和只有1页的效果:
<divue-page v-bind:currentpage="currentpage" v-bind:allpage="allpage" v-on:getajaxlist="getajaxlist"></divue-page>
直接粘贴就可以在另外的组件使用。
只有1页:
小于5页:
测试没有太大问题!
七.优化和改进建议
当然不是样式的优化,这个需要设计的参与,我们还是显示的优化和改进,比如:
我们是不是该有一个...
还有就是...
可以参考别的分页效果,然后你可以不断的改进!
八.完整代码
main.js:
